Subconscious develops TIMRUN, an inference runtime, and the TIM family of post-trained open models optimized for AI agent workloads rather than chatbots, offering on-GPU context compression that extends context windows and increases concurrency and token throughput. It serves developers building coding agents, agentic products, and edge deployments via OpenAI- and Anthropic-compatible APIs, and can act as a drop-in replacement for vLLM and SGLang.
